Interface PieURLGenerator

All Known Implementing Classes:

CustomPieURLGenerator, StandardPieURLGenerator

public interface PieURLGenerator

Interface for a URL generator for plots that use data from a PieDataset. Classes that implement this interface:

• are responsible for correctly escaping any text that is derived from the dataset, as this may be user-specified and could pose a security risk;
• should be either (a) immutable, or (b) cloneable via the PublicCloneable interface (defined in the JCommon class library). This provides a mechanism for the referring plot to clone the generator if necessary.
